Classification

Cerebral microarteriovenous malformation

Parafalcine arteriovenous malformation,….

Ruptured cerebral arteriovenous malformation

Unruptured cerebral arteriovenous malformation

AVMs that occur in the coverings of the brain are called dural arteriovenous malformation.

Deep arteriovenous malformation.

Motor area arteriovenous malformation.

Pathogenesis

Significant progress in the understanding of their pathogenesis has been made during the last decade, particularly using whole genome sequencing and biomolecular analysis ¹⁾

Clinical Features

Cerebral Arteriovenous Malformation Clinical Features.

Differential diagnosis

Primary lobar hemorrhages (usually due to cerebral amyloid angiopathy) are typically seen in elderly. Younger patients may also develop lobar haemorrhages, but in such cases they usually have an underlying lesion (e.g. cerebral arteriovenous malformation).

Treatment

Case reports

Bhanot et al. presented a patient with intraparenchymal hemorrhage due to cerebral arteriovenous malformation (AVM) who exhibited acute ST segment myocardial infarction (STEMI) after neurosurgery. Serial cardiac biomarkers and echocardiograms were performed which did not reveal any evidence of acute myocardial infarction. The patient was managed conservatively from cardiac stand point with no employment of anticoagulants, antiplatelet therapy, fibrinolytic agents, or angioplasty and recovered well with minimal neurological deficit. This case highlights that diffuse cardiac ischemic signs on the ECG can occur in the setting of an ICH after neurosurgery, potentially posing a difficult diagnostic and management conundrum ²⁾.
